TLP Simulation in ESD：How to generate the pulses，what do the pulses look like？

TLP Simulation in ESD：How to generate the pulses，what do the pulses look like？

A relay is used in the simulation model，should it be working all the time？ Continuely opening and closing？

I have built transmission line zappers for lab use in ESD
structures characterization. They do the job. All you are
looking for is an excess of voltage (so as to get breakdown)
and a constrained pulse width (which the electrical length
gives you).

I use a mercury-wetted relay between one end of the coax
coil and the "stinger". The other end has a 100Kohm series
resistor to the HV supply. All share commmon return with
the shield. A momentary switch energizes the relay coil
(w/ external +5V supply).

I believe in the past I have posted construction details
here.

Unless you are characterizing a multiple event scenario
you only close the relay once.

In simulation, forget all that - use a step voltage source
from zero to V(ESD) with a suitable risetime and all the
standard-model passives. Same difference but simpler.
